Abstract
A tool for tightening a band to a predetermined tension about an article by pulling the band through a buckle thereon includes a reciprocable feeder within a housing for gripping the band, incrementally pulling it into the housing, releasing it and then regripping it at another position while it is held by a supplemental grip within the housing. A handle pivotally mounted in the housing operates the reciprocable feeder through an operative connection responsive to the tension of the band in such manner that when a predetermined tension has been reached, the operative connection is disengaged while the band remains gripped by the feeder. The handle which operates the feeder may then be swung in the opposite direction to actuate a member which pushes the wrapped article around the nose of the tool in such manner as to bend the band about its buckle and thus to retain the desired tension therein, after which the band may be cut off at a position within the nose of the housing. A special feature of the tool is the construction and arrangement of the member responsive to tension for controlling the operative connection to the feeder, which comprises a plurality of Bellville washers arranged in series in such manner that when their preset thrust force has been overcome, they collapse and thereby release the connection between the handle and the feeder.
